Abstract

PCT No. PCT/FI92/00263 Sec. 371 Date Jun. 3, 1993 Sec. 102(e) Date Jun. 3, 1993 PCT Filed Sep. 24, 1992 PCT Pub. No. WO/9307685 PCT Pub. Date Apr. 15, 1993.A call control method for a radio system, wherein a half-duplex type mobile station (MS1, MS2) is commanded so as to clear a call on the radio channel of a base station (BS), by transmitting a disconnect signal to the mobile station (MS1, MS2) over the radio channel, the mobile station leaving the radio channel upon receiving the disconnect signal. In order to ensure that the disconnect signal is received by the mobile station, the field intensity received by the base station (BS) on the radio channel is measured immediately after the transmission of the disconnect signal, and the radio channel is released for the next call only when the measured field intensity falls below a predetermined threshold value.
